TO' ALL WHOM IT MAY- 'CONCERN:

Be it known that I, M. M. PREBLE, .of Kokomo, in the county of -Howard, and State of Indiana, have invented a new and useful Improvement in Fly-Traps; and I do' hereby declare that the following is n. full, clear, and exact description of the same, reference being had to the accompanying drawings,'in Which- Figure 1 is a perspective View oi' same.

Figure 2, a longitudinal sectionoil part of same.

Figure 3 is a slide.

The. same letters of reference denote identical parts in all the figures.

-To enable others skilled `in the art to make and use my invention, I will proceed to describe its construction and operation. i f

At one end of the top piece ci' box A, a tube, B, is fixed, reaching part way to the bottom, where honey7 molasses, o1' some other bait is put, in order to coax the ily down in the box. At the other end of the box A the end piece A is made of glass or other transparent' material. The ily hztvingsatisfied its appetite will not remain in the dark end of the box, but ly to the transparentend piece A', and trying to get out; will soon ind the opening C, through which it will pass into thev upper box E. Box Efis square; its sides 'are formed with wire screens, and moves on the top of box A in slides D, whereby'the-opening in the bottom of box E, and the corresponding opening in the toppiece `of box A may be regula-ted, and, if desired, entirely shut by moving box E for enough towards tube B. A slide, F, is inserted inv the top of the box under the box E, when in place forming e part of the top. This slide may be displaced by the slide G of the seme-size and moving in the same grooves. l

When the operator wants to kill the flies,v he fills the recess G in the slide G, with sulphur or other combustible substance, ignites it and pushes out slide F, inserting slide'Gr in its place. When the Hies are akilled, he separates the boxes, removes the dead ilies conta/ined in box. E, end putsit again into position.

What I claim as my invention, and desire te secure by Letters Patent, is-

The combination of the boxes A and `E, and slides Gr and F, the said parts being constructed and arranged substantially in. the manner and for the purpose set' forth;

In testimony whereof I have signed my name to this speciiication in the presence of two subscribing Witnesses.

M. M. PREBLE.
